Have read here no impact on ride quality an decreased performance. My experience was the opposite and wanted to share. Went with lowering springs on the F10 and prefer that for me.
Agree. Did H&R drop on my e60 M5 and loved it. Added aftermarket 20s on top of that and it was too harsh...regretted it.
